The problem is not feasible due to voltage constraints. Notice that voltages in
the power flow solution go as low as 0.813 p.u., but your case includes OPF
lower bounds on voltages at every bus of 0.95 p.u. Relaxing those voltage
constraints allows the OPF to converge.
define_constants;
mpc = loadcase('case_radial16');
mpc.bus(:, VMIN) = 0.85;
r = runopf(mpc);
